1604907 - TrouveThe general objective of the research project is to build an international collaborative framework between computational and experimental researchers in the fire science community around the topic of the experimental validation of computer-based fire models. The fire science community is small, fragmented and geographically dispersed. The present project is an effort to meet the resulting organizational challenge, to promote high levels of integration and coordination, and to provide a critical mass of researchers for topics central to computational fire research. The project will build on established programs in the U.S. aimed at producing computer models for engineering analysis of building fires, e.g., the Fire Dynamics Simulator developed by the National Institute of Standards and Technology and FireFOAM developed by FM Global. The project will contribute data and software modules to a new open-access web-based repository, develop physics-based guidelines for computational best practices, and produce a new series of online tutorials for graduate-level students. The project will also advance fundamental knowledge and develop engineering-level tools for the generic problem of fire spread along solid flammable materials.The project is proposed as part of a new initiative led by the International Association for Fire Safety Science (IAFSS) called "the IAFSS Working Group on Measurement and Computation of Fire Phenomena" (or the MaCFP Working Group). On the technical side, the project will focus on the problem of turbulent wall flames supplied with fuel vapors produced by the thermal degradation of solid flammable materials. The project will include performing both fine-grained (research-level) and coarse-grained (engineering-level) large eddy simulations. Coarse-grained simulations will require the development of new wall models for turbulent boundary layer flames. The simulation software adopted in the project is the free open-source fire model called FireFOAM. On the organizational side, the project will support the MaCFP Working Group effort, develop an open-access web-based digital archive of well-documented numerical simulations corresponding to selected target experiments, help identify key research topics and knowledge gaps in computational and experimental fire research, develop best practices in computational fire research, contribute to the organization of the new MaCFP workshop series, and help develop an international network of fire researchers and a community-wide forum for discussion and exchange of information.

1604907-研究项目的一般目标是在消防科学界的计算研究人员和实验研究人员之间建立一个国际协作框架，围绕基于计算机的消防模型的实验验证的主题。消防科学界很小，分散且在地理上分散。本项目是为了应对由此产生的组织挑战，促进高水平的整合和协调，并为计算消防研究中心的主题提供大量的研究人员。该项目将建立在美国既定计划的基础上，旨在生产用于建筑火灾的工程分析的计算机模型，例如，由国家标准技术研究所和FM Global开发的国家标准与技术研究所开发的火力动力学模拟器。该项目将为新的基于Web的开放式存储库，为计算最佳实践制定基于物理的指南，并为研究生级学生制作一系列新系列的在线教程。该项目还将推进基本知识，并开发工程级工具，用于沿着固体易燃材料传播的通用火灾问题。该项目是由国际消防安全科学协会（IAFSS）领导的一项新计划的一部分，称为“ IAFSS SOIFSS SOIAFSS测量和计算火灾现象的计算”（或MACFP工作组）。在技​​术方面，该项目将重点关注由固体易燃材料的热降解产生的燃料蒸气提供的湍流火焰问题。该项目将包括执行细粒度（研究级）和粗粒（工程级）大型涡流模拟。粗粒仿真将需要开发用于湍流边界层火焰的新壁模型。项目中采用的仿真软件是称为Firefoam的免费开源消防模型。 On the organizational side, the project will support the MaCFP Working Group effort, develop an open-access web-based digital archive of well-documented numerical simulations corresponding to selected target experiments, help identify key research topics and knowledge gaps in computational and experimental fire research, develop best practices in computational fire research, contribute to the organization of the new MaCFP workshop series, and help develop an international network of fire researchers and a community-wide forum for discussion and exchange of information.
